Title: Improvements in or relating to door springs
IPC: E05F1/12
Filed: 1922-11-02
Abstract: 204,940. Webberley, J. A., and Adams & Son, Ltd., J. Nov. 2, 1922. Operating doors by springs.-In floor springs of the kind described n Specification 14218/90, the arms b of convex form, which wind up the spring when the door is opened in either direction, are made concave at the ends c, as shown, or are formed in an equivalent manner, instead of being of a continuous convex form as represented by the dotted lines. By this arrangement, a stronger pressure is exerted by the spring to close the door from the fully-open position. The engagement is also designed so that the pressure of the spring on the roller e, which travels along the surface d, c of the lever b as the door is opened, is exerted in line or approximately in line with the path of movement y of the centre of the roller for approximately one-third of its movement from the fully-open position of the door towards the closed position of the door. The acting surface of the spring-controlled lever b may also be concave nearer the pivot h, or it may be constituted by two or more straight portions arranged at an obtuse angle or angles to each other, provided the construction is such as to operate in the manner previously described. In the complete apparatus shown in Fig. 1, a check l is employed, with the usual arms k arranged below the arms b and operable by the roller e. Specification 8072/85 is referred to.

Title: Improvements in or relating to tracers or duplicators for machine tools
IPC: B23Q35/36
Filed: 1950-12-08
Abstract: 692,642. Machine details; copying. ARMYTAGE, F. W. March 10, 1952 [Dec. 8, 1950], No. 30050/50. Class 83 (iii). [Also in Group XXIX] A fluid-pressure tracer valve for copying machine tools, such as milling machines or lathes, comprises inner and outer valve members axially reciprocable relative to one another by connections from the tracer stylus 25, one of the members, preferably the outer member, being built up from a series of rings 14. The rings 14 are chamfered at 16 and slotted at 17 on one face and are assembled in three pairs face to face to form channels leading to annular grooves in the valve body 1 from which a passage 9 leads to the pressure source and passages 5, 13 lead to exhaust. Slotted spacers 15 are fitted between the rings 14 to provide communication with annular grooves from which passages 7, 11 lead through a reversing valve 31 to the ends of the working cylinder. The inner valve member has external annular grooves 21 and is movable axially through about two-thousandths of an inch by either axial or lateral pressure on the stylus, the valve stem engaging the inner member by a conical- and spherically-faced connector such as 24 and being supported by a spherical bearing such as 26, or a curved flanged bearing, and an adjustable plug 27. An adjustable spring 22 tends to force the inner valve member downwards, and a pin-and-slot connection 29 prevents rotation of the valve stem. When the stylus is moving over the pattern without deflection, pressure fluid in the middle annular space 21 flows equally past the edges of the lands on the inner member and the edges of the middle pair of rings to the passages 7, 11 and thus to each end of the cylinder to hold it stationary, and the lands overlap the inner edges of the two outer pairs of rings to cut off the exhaust passages 5, 13. Deflection of the tracer moves the inner valve member up or down, opening one end of the cylinder fully to pressure and the other end to exhaust. Alternatively, internal ports may be formed in the inner member leading to annular ducts registering with corresponding ducts in the outer member.

Title: Improvements in or relating to nuclear reactor fuel elements and to strain indicators therefor
Inventor: WILLIAMS DAVID WILLIAM
IPC: G21C17/10
Filed: 1959-09-04
Abstract: 900,347. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Sept. 2, 1960 [Sept. 4, 1959 (2); Jan. 14, 1960], Nos. 30263/59, 30264/59 and 1387/60. Class 39 (4). A strain indicator for detecting localized swelling of the sheath of a fuel element comprises a body enclosing a detectable material or source of detectable material and having a part which, on the body being subjected to strain, is movable to release the detectable material. The fuel element shown in Fig. 1 comprises a uranium rod 1 encased in a sheath 2 provided with circumferential fins which are drilled to accommodate three equally spaced tubes 4 (of which one is shown) of alumina containing uranium wire 5. If a breach occurs in the sheath 2 during operation of a carbon dioxide cooled reactor the ingress of coolant may cause localized oxidation of the uranium rod which causes swelling of the sheath until a tube 4 breaks and releases into the coolant fission products' which are detected by the normal monitoring arrangements. Overall growth of the fuel element due to radiation does not break the tubes 4 as it is uniform over the length of the element. In another arrangement, Figs. 3 and 4 (not shown), a frangible tube containing uranium is arranged at right-angles to the fuel element supported by a bracket which may have sufficient play to take up overall growth. A single tube will monitor only a short length of the fuel element, so that a plurality of tubes are necessary to cover the whole element or alternatively the uranium rod 1 may be treated so that it oxidizes preferentially in the region of the tube or tubes. This treatment may comprise nitriding the rod except for a narrow band at each end or drilling one or more blind holes in the rod and filling them with a substance which oxidizes and expands in preference to uranium, e.g. a uranium carbon alloy. In a further arrangement, Fig. 6, a stainless steel capillary tube is bent into a ring surrounding the fuel element with one end 18 of the tube fitting inside the other end 17 which is enlarged. The end 18 encloses a uranium wire 19 and is provided with an aperture 21 which is normally situated inside the end 17. Growth due to oxidation causes the aperture 21 to be exposed, but normal growth is insufficient. By suitably positioning aperture 21 the indicator may be used to study normal growth, the degree of exposure of the aperture being measured by the quantity of fission products released.

Title: 2-methyl-8-phenyl-nonen-(7)-one-(4) and a process for the manufacture thereof
IPC: C11B9/00
Filed: 1958-09-24
Abstract: The invention comprises 2-methyl-8-phenylnonene-(7)-one-(4) useful in perfumery.  It may be prepared by heating phenyl methyl ethenyl carbinol with an ester of isovaleroylacetic acid, e.g. at 140-190 DEG C.; an isovaleroylacetate derivative is formed and undergoes rearrangement and decarboxylation on heating.  The conversion is preferably effected in the presence of an aluminium lower-alkoxide, e.g. aluminium isopropoxide.  Alternatively, the phenyl methyl ethenyl carbinol may be treated with a halogenating agent, e.g. a phosphorus halide or a hydrogen halide, to give by rearrangement a g - phenyl - g  - methyl - allyl halide which is then condensed with an alkali metal derivative of an isovaleroylacetic acid ester.  The desired ketone is obtained by hydrolysis and decarboxylation of the condensation product.  This may be effected in one step by heating with aqueous alcoholic alkali metal hydroxide or in two steps by mild saponification, e.g. with dilute alkali-metal hydroxide followed by decarboxylation by heating in aqueous acid solution, e.g. hydrohalic acid solution.
